Diameter measurements are to be
taken at the center (top to bottom,
side to side) of the specified fitting
section.
Note:
The example and drawing
on this page show an Aeroquip
MatchMate Plus fitting.
The crimp diameter is the
average of the four diameter
measurements around the fitting.
These measurements are to be
taken at the same relative locations
indicated in the illustration above.
Crimp ovality is the largest diameter
measurement minus the smallest
diameter measurement.
Example
GH781-12 hose with a 1AA12FJ12 fitting measures:
Measurement 1 =
31,57mm (1.243 in.)
Measurement 2 =
31,60mm (1.244 in.)
Measurement 3 =
31,65mm (1.246 in.)
Measurement 4 =
31,65mm (1.246 in.)
Measurement 1 + Measurement 2 + Measurement 3 + Measurement 4 = Crimp Diameter
31,51mm (1.243in) + 31,60mm (1.244in) + 31.65mm (1.246in) + 31.65mm (1.246in)
31.65mm (1.246in) – 31.57mm (1.243in) =
0,08mm (0.003in)

Note:
Danfoss defines the crimp
diameter as the average of four
measurements, not just one
measurement (see the “End View”
illustration above).
